Working Principle

The M39003/01-5424H are manufactured using a special anode construction consisting of a highly conductive tantalum powder core and an outer oxide layer that acts as the dielectric layer. When the proper voltage is applied to the anode, the dielectric oxide layer forms a semi-conductive structure that acts as the dielectric between the anode and the cathode.

The M39003/01-5424H uses a manganese dioxide cathode, which is a type of electrolytic conductor.When an electric potential is applied across the anode and the cathode, it causes a chemical reaction in the manganese dioxide electrolyte that releases an electron, which is then stored in the dielectric oxide layer. This process continues until the capacitance is fully charged. When the charge is decreased, the opposite process takes place and electrons are released.
